MC74HCT4852A

Analog Multiplexers/ Demultiplexers with Injection Current Effect Control with LSTTL Compatible Inputs Automotive Customized MC74HCT4851A, MC74HCT4852A This device is pin compatible to standard HC405x and MC1405xB analog mux/demux devices, but feature injection current effect control. This makes them especially suited for usage in automotive applications where voltages in excess of normal logic voltage are common. The injection current effect control allows signals at disabled analog input channels to exceed the supply voltage range without affecting the signal of the enabled analog channel. This eliminates the need for external diode/ resistor networks typically used to keep the analog channel signals within the supply voltage range. The devices utilize low power silicon gate CMOS technology. The Channel Select and Enable inputs are compatible with standard CMOS or LSTTL outputs. Features Injection Current Cross−Coupling Less than 1mV/mA (See Figure 6) Pin Compatible to HC405x and MC1405xB Devices Power Supply Range (VCC − GND) = 4.5 to 5.5 V In Compliance With the Requirements of JEDEC Standard No. 7 A Chip Complexity: 154 FETs or 36 Equivalent Gates NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free and are RoHS Compliant www.onsemi.com 16 1 16 1 MARKING DIAGRAMS SOIC−16 D SUFFIX CASE 751B 16 HCT485xAG AWLYWW 1 16 SOIC−16 WIDE DW SUFFIX C...
